I recently installed my pf100 Furnance. Has anyone noticed that the auger keeps dumping pellets in the burn pot after it starts shutting down? Is this normal? I would call and ask the people who sold me the furnance but I'm pretty sure I know more about the stoves then they did. They have been less than helpful this far. Also I've noticed that pellets with Alot of softwoods are considered premium grade? From years of burning wood stoves I noticed that softwoods produce more creosot and burn out quicker. If its the same with pellets I think I'll just go with the cheapest stuff I can find. What do ya'll think?
 
that is normal. It keeps the fuel moving so it dont burn back through the auger. It dont feed enough to sustaine a fire and allows the stove to shutdown slowly
 
Archie don't worry about the creosote with a soft wood pellet. They actually for the most part burn better and hotter than a hardwood. Creasote is not a real issue at all.
 
My 100 does the same; continuing to feed pellets for a while. Takes almost an hour for it to completely shut down. Never really timed it.
 
Exoilburner, out of curiosity, what part of the country are you in and how many pellets do you go through? I'm in the middle of NC we usually have a mild winter. I was trying to calculate how many wood pellets I would go through?

I am pretty far north in western Washington west of the Seattle area. I'm not sure I can give you an accurate answer because I have always turned my furnace down to 55Df overnight and back to 68 first thing in the morning. Thanks to this forum I learned if I leave my furnace at 70 all of the time I burn less fuel. This year I tested both methods when the outside temperature was the same and I did burn less fuel when leaving the thermostat at 70 for 24-7.

With that in mind the year before last was a pretty normal winter and I burned 6 tons in 12 months. Last year was colder and I burned a few bags under 7 tons. Both of those years I was NOT leaving the thermostat at 70 so for both of those years I could have had some improvement of fuel usage.
 
Wow, y'all run your furnace all year? Not much of a summer? There is 7 months of the year it's way to hot here. I'm hoping to get out with
around 2 tons, but I guess we will see.
 
Does your breather flap on the door stay partially open all the burn time even if you are oak'd or not?

I finally started looking at this. I hear it flutter on a cold startup just after the pellets ignite.

The flutter is somewhat normal. During a cold start your air pressure is negative in the system at a lower measure. When fire is introduced you have a flux of positive pressure Which may bring your negative closer to zero, as son as the burst of heat is expelled your pressure returns back negative but not quite as low as when it was cold. The flutter is this change which is occurring.

Awesome, thanks for that info.

I run it 10 months. Sept thru June. In the sholder seasons on some days I don't need to run it; and colder days it runs on minimum burn.

Mine does the same as yours. OAK is hooked up.
 
Exoilburner, that would put it at an average of .7 ton a month, which would put me at 3.5 tons for the winter months here. I was hoping to do alittle better than that, but I guess I will really have to wait and see. I will know more next winter. Where I'm from in NC it's rare to meet someone that even knows what a wood pellet stove is. So getting advice from someone from my climate is near impossible... Thanks for the help!

My home has very little insulation so you may do better than I do.

Glad to help. Thats what we are here for. The people on this forum have saved me hundreds of dollars. I have learned so much here that I am now able to negotiate on par with my dealer, their service department people, and the manufacturer. Before that I pretty much had to take their word for everything.
